53<H2>Description</H2>
54<P>
55Registers a dynamic module with the EL library.<BR><BR> The <code>EL_Link</code> function loads the dynamic module using the read function specified by the developer. The <code>EL_LinkFile</code> function loads the dynamic module to be registered from ROM. The <code>EL_LinkImage</code> function uses a dynamic module that has been loaded into memory. <BR>You must secure a region for <SPAN class="argument">buf</SPAN> that is larger than the size determined by the <a href="EL_CalcEnoughBufferSizeforLink.html"><CODE>EL_CalcEnoughBufferSizeforLink*</CODE></a> functions. Also be aware that, because <SPAN class="argument">buf</SPAN> is where the dynamic module is registered, if the <code>EL_LinkImage</code> function performs the task of registering the dynamic module, you temporarily need an additional buffer (<SPAN class="argument">obj_image</SPAN>) equal in size to the dynamic module (ELF file).
56<P><B>Note:</B> You can use a debugger to debug the dynamic module only if the <code>EL_LinkFile</code> function has been used.
